,  , The Indian wax scale, Ceroplastes ceriferus (Fabricius) is redescribed so that it can be distinguished from Ceroplastes pseudoceriferus Green, which it most nearly resembles and has been confused with in Korea. A dichotomous key, photographs, and DNA barcode information are also presented for identifying three Ceroplastes species from Korea.
Thirteen species of mealybugs were intercepted in quarantine at Korean ports of entry on plant materials from China over the past 9 years (2000-2009). Of these, Phenacoccus madeirensis Green has been newly reported in China through this study. This list and key are provided to assist in identifying intercepted specimens of mealybugs from China.
